camera¶

A ctypes based interface to Hamamatsu cameras.

Original Notes:

(tested on a sCMOS Flash 4.0).

The documentation is a little confusing to me on this subject. I used c_int32 when this is explicitly specified, otherwise I use c_int.

FIXME: I’m using the “old” functions because these are documented.
Switch to the “new” functions at some point.

FIXME: How to stream 2048 x 2048 at max frame rate to the flash disk?
The Hamamatsu software can do this.

TODO:

Review what is actually needed and get rid of unused functions.

Classes

HamamatsuCamera(camera_id[, logger])

HiSeq Camera.

exception pyseq.dcam.DCAMException(message)¶: Camera exceptions.

class pyseq.dcam.DCAM_PARAM_PROPERTYATTR¶: The dcam property attribute structure.

class pyseq.dcam.DCAM_PARAM_PROPERTYVALUETEXT¶: The dcam text property structure.

class pyseq.dcam.HCamData(size)¶: Hamamatsu camera data object.

class pyseq.dcam.HamamatsuCamera(camera_id, logger=None)¶

HiSeq Camera.

allocFrame(n_frames)¶

Allocate memory for n_frames.

Parameters

n_frame (int): Number of frames to allocate memory for.

Returns: - int: 0 if no errors.

getFocusStack()¶

Return stack of images across all channels.

Parameters:

image_path (path): Directory to save images.

Returns:

array: Object array with objective stack images

getFrameCount()¶: Return number of frames (int) that have been taken.

getFrameInterval()¶: Return the frame interval (float, seconds per frame).

getFrames()¶: Gets all of the available frames.

get_status()¶

Return the status of the camera.

The camera must be “ready” to start imaging.

Integer	Status
0	error
1	busy
3	ready
4	unstable

Returns:

int: Integer corresponding to status of camera.

message(text)¶: Log communication with camera or print to console.

saveImage(image_name, image_path)¶: Gets all of the available frames as numpy array and saves as TIFFs.

setAREA()¶: Switch camera to AREA imaging mode, return True is successful.

setTDI()¶: Switch camera to TDI imaging mode, return True is successful.
